Dont give use half a story.

What are the symptoms, and what are all the codes in the drivetrain.

My 3.2 v6 auto lpg has the EML on all the time, if I reset the ECU it comes back after 30miles or so, I put it into sport mode to over take when it got to 6000 rpm the EML light flashed I lost all power and the engine sounded like it was running on three cylnders.  I pulled over disconnected the battery for five mins, after that it was ok then it happened again when I accelerated at high revs. The last time it happened when it changed up a gear there was a thud. There were no other fault codes just the ones mentioned earlier, any help would be much appreciated.

First thing to do is to drive it on petrol for a week or so and see if any of the problems occur on petrol too, IMHO.

P0420 and P0430 are normal on a 3.2 V6 because the pre-cats fail. Not anything to be concerned about although the lambda sensors can be relocated to prevent the codes being raised.

Ah, the full story :y

As Kevin Wood says, find out if it does it on petrol - this will help to pinpoint it to a 'standard setup' problem, or an LPG calibration problem.
